How does gravity work at the (sub)atomic scale? Do Newton’s laws apply, as they do for stars and planets, or do different laws apply at this scale? This important question is being addressed by scientists from the Institut Laue-Langevin (ILL) and from the Vienna University of Technology.
Using high-speed videos, Pedro Reis and Roman Stocker from the Massachusetts Institute of Technology has shown that lapping cats are masters of physics. Every flick of their tongues finely balances a pair of forces, at high speed, to draw a column of water into their thirsty jaws.
